Phys.org  August 4, 2022 Various artificial visual systems including those based on human eyes, insect eyes and fisheyes have been developed. However, attempts to develop systems for both terrestrial and aquatic environments and bioinspired electronic eyes are restricted in their maximum field of view to a hemispherical field of view (around 180°). An international team of researchers (South Korea, USA – UT Austin, MIT) has developed an amphibious artificial vision system with a panoramic visual field inspired by the functional and anatomical structure of the compound eyes of a fiddler crab. They integrated a microlenses array with a graded refractive […]
